bpo-42367: Restore os.makedirs() and pathlib.mkdir() ability to apply *mode* recursively via a new parent_mode= keyword argument.
(cherry picked from commit 9770e32ce0)
+ Make Path.mkdir parent_mode tests umask-independent
test_mkdir_with_parent_mode, test_mkdir_parent_mode_deep_hierarchy and
test_mkdir_parent_mode_same_as_mode assert exact directory mode bits but
did not pin the process umask. On buildbots running with a restrictive
umask (e.g. 0o077) the 0o755 leaf was masked down to 0o700, failing the
assertions. Wrap them in os_helper.temp_umask(0o022), matching the
other umask-aware mkdir tests in this file.

gh-87451: Apply CVE-2021-4189 PASV fix to ftplib.ftpcp() (GH-149648)
ftpcp() called parse227() directly and passed the source server's
self-reported PASV IPv4 address to the target server's PORT command,
bypassing the CVE-2021-4189 fix that was applied only to FTP.makepasv().
A malicious source FTP server could use this to redirect the target
server's data connection to an arbitrary host:port (SSRF).
ftpcp() now uses the source server's actual peer address, honoring the
existing trust_server_pasv_ipv4_address opt-out, the same as makepasv().

* gh-149504: Fix re-entrancy bug when .pth/.start file invokes site.addsitedir() (#149659)
* Add re-entrant tests for gh-149504
* Add end-to-end integration test coverage
This ensures that future whitebox internal test changes do not regress the
public surface semantics.
* Implement a state class to process .pth and .start files
By using this state class and managing implicit and explicit batching, we make it structurally
impossible to get bitten by re-entrant site startup processing.
Fixes#149504
(cherry picked from commit b162307d7f)
* Add myself back to CODEOWNERS
RFC 2047 Section 6.2 requires that "any 'linear-white-space' that
separates a pair of adjacent 'encoded-word's is ignored." The modern
header value parser correctly implements that for unstructured headers,
but had missed a case in structured headers. This could cause a parsed
address header to include extraneous spaces in a display-name.
Switch to @bitdancer's fix from review feedback. Recharacterize space
between ews as fws after parsing in get_phrase.
RDM: This fix is dependent on the fact that "subsequent" atoms will never have
leading whitespace because that's been consumed already. I don't think
it's worth adding extra code for the possibility of leading whitespace
because the parser won't produce it. It's a bit of parser fragility in the
face of code changes, but I think that's a minor concern given the
parser design (which is that it consumes whitespace greedily)

gh-149496: Fix MacOSTest.test_default regression when BROWSER env var is set (GH-149579)
gh-149496: Fix MacOSTest.test_default failing when BROWSER env var is set
MacOSTest.test_default calls webbrowser.get() and asserts it returns a
MacOS instance. When BROWSER is set in the environment (e.g. BROWSER=open,
a common macOS workaround for the old osascript-based implementation),
register_standard_browsers() registers a GenericBrowser as the preferred
browser instead, causing the assertion to fail.
This is a regression introduced in gh-137586, which added MacOSTest and
moved test_default into it from MacOSXOSAScriptTest. MacOSXOSAScriptTest
had an identical setUp() guard added in gh-131254 specifically to fix this
same failure. The guard was not carried over to MacOSTest.
Add setUp() to MacOSTest to unset BROWSER for the duration of each test,
restoring the isolation that was already established as the correct pattern
for macOS webbrowser tests.

In free-threaded builds, concurrent calls to PyDict_AddWatcher, PyDict_ClearWatcher, PyDict_Watch, and PyDict_Unwatch can race on the shared callback array and the per-dict watcher tags. This change adds a mutex to serialize watcher registration and removal, atomic operations for tag updates, and atomic acquire/release synchronization for callback dispatch in _PyDict_SendEvent.

gh-149486: tarfile.data_filter: validate written link target (GH-149487)
The data filter rewrote linknames with normpath() but ran the
containment check against the un-normalised value, and computed a
symlink's directory before stripping trailing slashes. Both let a
crafted archive create links pointing outside the destination. Also
reject link members that resolve to the destination directory itself,
which could otherwise replace it with a symlink and redirect all
subsequent members.

gh-149430: Fix edge-cases in `profiling.sampling` outputs (GH-149431)
The line highlights on the heatmap are driven by the URL hash and the
`:target` selector. When clicking a caller/callee link for the line that
was already selected, the hash doesn't change, so the browser keeps the
existing target state and doesn't restart the animation. Due to this the
highlight only works the first time.
With this fix, line navigation goes through JavaScript. If the target
URL already points to the current location, the highlight is replayed by
clearing the animation, forcing style recalculation, and restoring it.
The `baseline_self` variable isn't initialized for structural elided
roots. This variable is accessed later unconditionally and leads to a
crash.
The child process ends up being invoked with `--diff_flamegraph` instead
of the correct argument.
